WIND-GUARD.

' SPECIFICATION forming part of Letters Patent No. 424,212, dated March2,5, 1890.

Application med May 2s, 1889.

Serial No. 312,463. (No model.)

To @ZZ whom it may concern.-

Be it known that I, JOHN KEANE, a citizen of the United States, residingin the city and county of San Francisco, and State of California, haveinvented certain new and useful Improvements in find-Guards for Chimneysand ventilators, of which the following is a specification.

4My invention relates to wind-guards or protectors for chimneys andventilator-pipes, and more particularly to the production oi' animprovedguard for use on ships and vessels.

It consists in certain novel construction and combination of parts, ashereinafter fully described, producing a guard that is especiallyadapted for use on shipboard to secure constant upward draft in asmoke-pipe or a ventilator-pipe.

The nature of my said invention and the manner in which I proceed toconstruct and produce the same will be understood from the followingdescription, in which the accompanying drawings are referred to byfigures and letters.

Figure lis a side elevation of my improved guard for a chimney orsmoke-pipe. Fig. 2 shows a modification that is designed for use on theend of aventilator-pipe on shipboard.

A is the end of the guard that is set directly upon the pipe to beprotected, for which purpose it should have suitable size andform tomakea close .fit over the end of thepipe. The upper end of this part isturned downward to produce the short limb AX, and the end of this siphonportion is turned outward to bring the mouth a2 substantially atrightangle to the long limb A. Perpendicularly across this upper end ofthe siphon, to stand parallel with the main portion A, is iiXed a shortpipe B, open at both ends, and having about the same diameter as theshortdmb pipe. These parts form the body of the guard, and are arrangedas shown in Fig. 2 of the drawings, `with the short limb of the siphonand the perpendicular pipe across its end placed closely against eachother; or, as shown in Fig. l, the bends of the short limb may be largerand the parts set oif with a space be*- tween the sides of the pipe andthe short limbA The same operation and results are obtained D, of suchsize that it will close the pipe B below this side opening when turneddown t0 uncover the opening. In this arrangement the pipe B is setclosely against the short limb, so that the opening C is readily madethrough the pipe into the Siphon. rThe damper D is counterweighted, asshown in Fig. 2, and will be :normally held to close the opening C, andwill also close the pipeB when turned down and leave Athe opening Copen, thus making the draft more direct from pipe A to the upper end ofpipe B when down and more circuitous when raised to close the opening C,thus regulating the draft and prevent ing gusts when desired. Thisopening and damper are not .required where the guard is used on achimney or smokepipe; but in such application of the guard it will befound desirable, especially on shipboard, to provide screens on the endsof the pipe B, and particularly on the lower ends of the pipe, to retainthe soot, and thereby secure greater cleanliness in the vicinity of thecooks galley and other parts where smoke-pipes are brought outside abovedeck. The screens E E* are therefore provided for covering either thebottom end or both ends of the pipe B, if found necessary.

The screen E is formed with a closed panshaped bottom e to catch andretain the soot and drippings, and has openings eX in the sides coveredwith wire gauze. Any suitable fastenings can be used to hold it in placeon theend of the pipe and to allow it to be removed for cleaningdsuch,for instance, as the well-known pin and bayonet-slot fastening, as Ihave represented in Fig. 1.

Instead of placing a screen on the top of the pipe, the usualcone-shaped cap G can be fixed over the open end to deiiect the air andkeep ont rain. The upper end of this pipe is also made funnel-shaped, asshown in Fig. 2,

IOO

after the manner of forming the mouths of ventilator-caps and forthesame purposenamely, to increase the area of the inlet.

As thus constructed and applied, my improved guard Will be found tooperate effectively in all situations where a smoke-outlet oraventilator is exposed to cross-drafts or deected currents. It producesconstant upward draft by suction in Whatever direction the Wind orair-currents may strike it, While complete exclusion of rain or of theseais secured. 4

Having thus fully described my invention, what I claimand desire tosecure by Letters Patent, is-

l. In combination with a Wind-guard com posed of the tWo parallel pipesA B and the short limb AX, the screen E, having a close bottom e andscreen sides adapted tov be applied to and removed Afrom the lower endof the pipe B, as and for the purpose set forth.

2. In combination with a Wind-guard composed of the two parallel pipes AB and the short limb AX, having opening C in the Wall between the shortlimb and pipe B, and a damper D fitted thereto, and adapted by its sizeand position to close said opening when turned up and to shut the pipe Bat a point below said opening when turned down, i

substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand andseal.
